What the figures tell you Broilers are kept in large numbers. Therefore, problems that start small are often noticed (too) late. Often the birds’ behaviour will not indicate possible problems such as whether they are eating too little. But minor changes may be a precursor to e.g. severe gut problems. By recording and evaluating objective house data daily you can intervene much earlier and avoid problems or expensive treatments.
Set your own standards Compare your data with the standards recommended by the breeding organisation. But it’s actually more important that you also set your own standards and to, for example, compare figures and data with previous flocks. Compare your practices with those of nearby farms who keep the birds in a similar manner.

Where and how? Make it easier to spot changes by always recording the data at the same time every day. Generally a marked change in feed or water consumption is the first sign that there is a health, feed, ventilation
or temperature problem. Make sure that it is easy to record data at the location where you make the observations i.e. hang a card on the door, keep a water list at the water meter, etc. Or alternatively, use a centralised (digital) form that is filled out during inspection rounds.

Broiler weight scales. Check all weighing equipment regularly to make sure it is working properly. Not only is faulty data worthless, it also gives you incorrect signals, which is much more serious.
Record the data where you collect it to prevent loss of information. In this case: in the poultry house.
